  49. 49. 2 Phase 2: Design the User Interface ►Principles of User Interface Design • The GUI should be easy to use and follow ►Users will not be satisfied with the application if the user interface is not easy to use • Three primary means of interacting in a user interface are the keyboard, a pointing device, and voice input • Use of the interface should feel natural and normal • Provide the most appropriate object for each requirementChapter 2: Program and Graphical User Interface Design 49
  50. 50. 2 Phase 2: Design the User Interface • Once an object is used for a particular purpose, then that object should be used for the same purpose throughout the program interface • Arrange objects in the sequence in which they are used • The interface should be kept as simple as possible, while maintaining functionality • The user interface should be intuitiveChapter 2: Program and Graphical User Interface Design 50
